Compare
Rework CI workflow to follow Rerun's patterns: - Renamed build-and-publish.yml → build-viewer.yml - Added push-to-main trigger alongside PR and tag triggers - Simplified wheel build: removed redundant --interpreter flag (bindings='bin' produces py3-none universal wheels) - Added concurrency group to cancel stale runs - Added workflow_dispatch for manual triggers - Cleaner job structure: check → build-wheel → test-wheel → publish → release - Uses GitHub Artifacts for wheel storage (not GCS) - Publish to PyPI via maturin upload on v* tags only Rerun's reusable_build_and_upload_wheels.yml cannot be called directly because it is tightly coupled to building rerun_py (uses pixi, GCS sccache, rerun-cli download, and rerun_py-specific feature flags). Instead, this workflow follows the same structural patterns: platform matrix, manylinux_2_28 compat, artifact upload per platform.

Add [project.optional-dependencies] viewer = ['dimos-viewer>=0.1.0'] to enable 'pip install dimos[viewer]' for the interactive Rerun viewer with click-to-navigate support. Note: dimos-viewer is not yet published to PyPI. The uv.lock will resolve after the first release of dimos-viewer (see dimensionalOS/dimos-viewer#4). Once published, run 'uv lock' to update the lockfile. Relates to DIM-646

Problem
Closes DIM-646
The custom Rerun viewer binary requires users to compile from source. This PR adds maturin-based Python packaging so
pip install dimos-viewerjust works.Changes
